1.4 PURPOSE OF THIS MANUAL
The air conditioning system should only be installed by qualiîš¿ed
personnel, with the necessary resources, tools and equipment,
who are familiar with the safety procedures required to success-
fully carry out the installation.
PLEASE READ AND FAMILIARISE YOURSELF WITH THE
MANUAL BEFORE STARTING WORK ON THE INSTALLATION
OF THE AIR CONDITIONING SYSTEM. Failure to observe the
instructions for installation, use and operation described in this
Manual may result in operating failure including potentially seri-
ous faults, or even the destruction of the air conditioning system.
It is assumed that the air conditioning system will be installed and
maintained by responsible personnel trained for the purpose. If
this is not the case, the customer should include all the safety,
caution and operating signs in the native language of the person-
nel responsible.
Do not install the unit in the following places, as this may lead to
a îš¿re, deformities, rusting or faults:
• Places where oil is present (including oil for machinery).
• Places with a high concentration of sulphurous gas, such as
spas.
• Places where ammable gases may be generated or circu-
late.
• Places with a saline, acidic or alkaline atmosphere.
Do not install the unit in places where silicon gas is present. Any
silicon gas deposited on the surface of the heat exchanger will re-
pel water. As a result, the condensate water will splash out of the
collection tray and into the electrical box. Water leaks or electrical
faults may eventually be caused.
Do not install the unit in a place where the current of expelled
air directly affects animals or plants as they could be adversely
affected.
